Description

Lichee Nano is an SD Card Sized Linux Development Board Powered by Allwinner F1C100s ARM9 Processor. This is an exquisite small board measuring only 2.54cm X 3.3cm, which is equivalent to the size of an SD card.
The Board also supports:

CSI Camera
Full HD Video Engine (H.264, H.263, JPEG / MJPEG, etc.)
RGB LCD Interface
CVBS Input / Output
Audio Codec
I2S / PCM
SD / eMMc

This is thanks to the main chip of Litchi Pie Nano-Quanzhi F1C100s; Arm9 architecture, 16KB D-cache, 32KB I-Cache, support boot from SPI Flash or TF card, and support USB OTG loading update.
Pin Diagram

Litchi Pie Nano continues the clever design of the previous generation, 2.54mm common pin welding holes + 1.27mm stamp hole patch design, which is convenient for you to DIY while supporting patch production and making more complex applications.
In addition, since the first generation of the Litchi Pie, it has been constantly adapting to peripherals and has mature modules that have been extensively verified by TF-Wifi, RGB to VGA, 40 pin RGB, LCD, RGB to GPIO, Camera, etc.
Litchi Pie Nano is now officially supported by RT-Thread. You can apply RT-Thread??s rich ecological resources to quickly and efficiently prototype design.

Features:

CPU -Allwinner F1C100s, ARM 926EJS processor, up to 900MHz
Display ?? 40-pin RGB LCD FPC connector supporting 272×480, 480×800, 1024×600
